Benefits of technology

The present invention is a warning sign that can automatically remove itself after a set period of time, making it safer and more visible. It can be mounted at strategic locations and can be attached to door jams or ceilings to avoid any trip hazards. The main benefits of the invention are its improved visibility, safety, and sanitation as it is not set on the floor.

Problems solved by technology

Floors that are wet, following a cleaning or due to a spill, pose a safety hazard for pedestrians.
Such conditions may result in accidents and injuries, and give rise to law suits against the building owners and / or operators.
One of the major drawbacks of the warning signs is that they are not immediately removed once they are not needed.
This may cause issues in transportation of patients and the wheelchairs.
In addition, if the signs are left for long time, they may even cause contamination in places like hospitals.
Another issue with excessive use of warning signs is that it creates complicity towards its message and presence.
Therefore, people may not pay enough attention to them after a while.
They themselves may also become a trip hazard.

first embodiment

[0035]FIG. 1 shows a wet sign 10 based on the present invention. A person which is responsible for the cleaning of the hallway 200 pulls out the wet sign 10 which hangs on the hallway 200. The wet sign 10 has a built-in mechanical timer in the housing, which after a pre-set period of time (for example one hour) it will roll in inside the housing.

[0036]Again as shown in FIG. 1, there are two wet signs 10 which one of the sign is pulled out and sets for a pre-set period of time and the other one is pulled in after the pre-set period of time.

[0037]FIGS. 1-6 show the first embodiment of the present invention. The first embodiment of the present invention is a timer caution sign 10, which comprises of a housing 11, which has a distal end 12, a proximal end 13 and a slot 14 is formed in the housing 11 in a position such that an elongate strap 20 extends and retracts through the slot 14. The elongated strap 20 is housed inside the housing 11. The elongated strap 20 is extendable from the h...

second embodiment

[0042]In the present invention, the mechanical timer can be replaced by an electro-mechanical timer 50 as shown in FIG. 7. The electro-mechanical timer 50 can be programmed to trigger the releasing part 41 to retract the caution sign 20 into the housing 11. The electro-mechanical timer 50 further has a communication means such as Bluetooth or Wi-Fi to communicate with a mobile phone or a computer. The mobile phone or the computer can control the operation of the electro-mechanical timer 50.

[0043]The electro-mechanical timer 50 in the present invention can be a cam timer for controlling a sequence of events automatically. An electric motor in the cam timer drives a shaft on which a series of cams with pegs along its surface are arranged. Indentations or protrusions on the cams operate the switches at different times.

[0044]As shown in FIG. 8, the caution sign 20 of the present invention can be retracted by the mobile phone 60 or by the computer network through a user 100. One of the e...

Abstract

A retractable warning sign having a timer, comprising: an elongated housing having a longitudinal slot, a distal end, and a proximal end; a retractable strap wound around a spool assembly and housed inside said elongated housing that extends and retracts through said longitudinal slot; a timer connected to said spool assembly to set a retraction time for said retractable strap; a hinge assembly coupled to said proximal end of said elongated housing to provide a translational movement for said elongated housing, and an attachment mechanism to attach said elongated housing on a wall or a ceiling or a window.

Description

FIELD OF THE INVENTION[0001]The present invention relates in general to warning signs and in specific to an automatic rolling sign with a timer.BACKGROUND OF THE INVENTION[0002]The warning signs are frequently used to alert pedestrians about dangerous or harmful conditions such as a wet or slippery floor. Wet surfaces are commonly marked by safety markers in restaurants, grocery stores, factories, shopping malls, hospitals and other areas where foot traffic is prevalent and spills may occur. Their purpose is generally to prevent people from coming into contact with the wet surface so as to prevent slips and falls due to the slippery surface caused by the wetness.[0003]Floors that are wet, following a cleaning or due to a spill, pose a safety hazard for pedestrians. Such conditions may result in accidents and injuries, and give rise to law suits against the building owners and / or operators.[0004]Typically, these warning signs include collapsible safety markers, which are foldable, pl...
